Description

Supraglottic airway devices constitute a fundamental component of modern airway management, with laryngeal mask airway (LMA) devices being widely implemented across various clinical anesthesia settings. The advent of video-assisted LMA systems has enabled real-time visual confirmation of device insertion and positioning, thereby enhancing procedural accuracy. Beyond their potential to improve patient safety outcomes, these advanced systems provide a pedagogical advantage by facilitating visual feedback during training, thus supporting the optimization of skill acquisition and educational effectiveness in airway management.

The primary aim of this study is to evaluate the learning curve of anesthesia residents during the placement of video-assisted laryngeal mask airway (video LMA) devices and to objectively assess our routinely implemented training protocol by systematically recording the process. Video-assisted airway devices, particularly video LMA systems, offer several advantages over conventional blind techniques. These advantages include higher success rates of insertion, shorter placement times, direct visual confirmation of proper positioning, and a reduction in airway-related complications. Today, many experts acknowledge that video-assisted techniques represent a new standard in supraglottic airway management with respect to both patient safety and educational utility.

Successful execution of video LMA placement requires the acquisition of three core and interrelated technical skills: obtaining an adequate view during insertion, correctly interpreting the visual information to assess device position, and performing precise manipulation through hand-eye coordination. These competencies are especially crucial for anesthesia residents undergoing training and must be effectively acquired during their educational development.

The use of LMA is common in routine elective surgeries. Video-assisted LMA systems are particularly beneficial in educational settings, as they provide real-time visual feedback for the operator and facilitate instructor-led guidance. Before initiating video LMA applications, residents in our institution undergo structured theoretical and practical training, followed by supervised clinical practice under the guidance of experienced anesthesiologists and academic staff. Through this study, we aim to analyze the learning curves of residents and objectively evaluate the effectiveness of the educational approach.

This study aims to evaluate the learning curves of residents in video laryngeal mask airway (LMA) placement and to objectively assess the effectiveness of the training program. This prospective observational study will be conducted with the participation of anesthesiology and reanimation residents at a university hospital. First- and second-year anesthesia residents with no prior experience in video LMA insertion will be included in the study.

Each participant will perform a predetermined number of video LMA insertions (≥10 cases) in adult patients undergoing elective surgery. For each attempt, success or failure, insertion time, quality of ventilation, and the occurrence of complications such as bleeding or gag reflex will be recorded. Success criteria will be based on standards defined in the literature, and all procedures will be carried out under the supervision of an experienced instructor.

Using the collected data, each participant's learning curve will be analyzed using the CUSUM method. This will allow for statistical assessment of the number of cases required for the learning process to reach a stable plateau.
